It was originally a 1995 level designed by Michael Bukowski, a programmer for the Doom 3 port with Vicarious Visions. A bugfixed PC version can be downloaded at ClassicDoom.com alongside the Xbox version; in both cases, the level is located on MAP01.

The Xbox 360 port of Doom II and the Doom 3: BFG Edition version also contain this level. However, it is inaccessible in both versions because the exit switch leading to the level in MAP02 is inoperable (in the Xbox 360 version, it does nothing; in the BFG Edition version, the switch causes MAP02 to be restarted).

When you start the level, enter the room directly to the north, and go through the teleporter. After this, use the teleporter to the east, and flip the switch you find in the next room. A compartment will open nearby containing a medikit and a switch. (sector 11)

Flip the switch in secret #1. When you access the red keycard, you will find that a closet has opened behind the keycard to reveal a rocket launcher and a backpack. (sector 26)

On the intermission screen, the par time for this level is initially displayed as :00, but quickly switches to SUCKS. This normally only appears with the Time readout when the time taken to finish a level exceeds one hour.

In the Xbox version of the level, the teleporter in front of the yellow keycard door does not work. This is because while all of its linedefs are correctly marked as type 97 (teleports,) they are not tagged to any sector. Consequently, if you arrive here without the yellow keycard, it will become impossible to finish the level. In the PC version of this level, these linedefs are tagged, allowing you to escape from the room if you arrive without the keycard; you will be taken to the eastern section of the map.
